The constantly increasing need for computing power is driven by the creation, development, and deployment of various processor intensive tasks. In most cases, individuals, businesses, and even academia find it hard to harness increased computing power without making a significant investment in the infrastructure, which could include supercomputers. SONM, a blockchain powered distributed computing platform has a solution that might solve the issue for many.

SONM is a universal fog supercomputer that allows people who are part of the network to contribute unused processing power on their devices and help those who need it. The peer-to-peer network can be used for a range of applications including video, CGI rendering, DNA analysis, complex scientific calculations and even to host websites. Like any other blockchain system, SONM also rewards the community with its namesake crypto tokens for sharing their processing power. Continue reading…

The Network File System (NFS) was originally developed by SUN Micro-systems that allows communications between Linux/Unix systems. It allows you to mount your local file systems over a network and remote hosts or clients to interact with them as they are mounted locally on the same system.

Benefits

>> Central Data Management.
>> Allows local access to remote files transparently.
>> Very good for local or reliable connections

Important NFS configuration file

/etc/exports : All files and directories which need to be exported are defined in this which is located in server.

Here we are going to share the /home directory in the server using NFS. To share this we need to add this directory to be shared and the details of how it is shared in /etc/exports file.

vi /etc/exports

Here we are going to add the below line in the above file

/home 192.168.0.xx(rw,sync,no_root_squash,no_subtree_check)

rw : This allows the client to read and write in the shared directory
sync : Sync confirms requests to the shared directory only once the changes have been committed.
no_root_squash : This allows /home accessed as root.
no_subtree_check : This option prevents the subtree checking. When a shared directory is the subdirectory of a larger filesystem, nfs performs scans of every directory above it, in order to verify its permissions and details. Disabling the subtree check may increase the reliability of NFS, but reduce security.

Once you entered the above entry, we need to export them by using below command.

exportfs -a

Note : We need to run this command for every update we make in the /etc/exports file.

exportfs -r

Client

yum install nfs-utils nfs-utils-lib

Then we need to create a directory in client system where we want to mount NFS shares. For e.g.:
